Diane says her 17-year-old daughter, Brianna, is an out-of-control drug abuser who has run away from home at least five times and does not respect authority. She says she recently forced Brianna into a youth shelter, hoping it would scare the teen straight, but nothing has changed — and she fears for her daughter’s life. Diane also claims her ex-husband, Michael, abandoned Brianna after their divorce — and she feels that contributed to the teen’s downward spiral. How does Michael respond? And, what ownership does Diane take in the situation? Brianna says her mother is overreacting and insists she’s just living the partying lifestyle by using Xanax, Molly, marijuana, PCP, heroin and alcohol. But is there something deeper at play? Emotions run high when the family comes together on Dr. Phil’s stage — and an unexpected moment happens. Will Brianna realize the dangers she’s facing and get the help she needs?
